AI animated book covers - marketing flop?

I think I remember Thomas recommending using AI to animate your book cover (though I can’t remember when he said this) and using that for marketing purposes. We tried that as an IG ad this week, and the response has been very negative, at least as far as comments go. (I thought the video clip looked really cool). People are extremely hostile to AI, even if it’s based on an image we hold full rights to that was hand drawn. Has anyone else experienced this? This might have the opposite effect than we intended.
